PROCESS OF COLLECTING AND UTILIZING CARBONlC-ACID GAS FROM ACIDULOUS' SPRINGS.

SPECIFICATION forming part of Letters Patent No. 259,219, dated June 6,1882.

Application filed m 1, 1882. (No model.)

7 To all whom z'tmay concern:

Be it known that I, CARL H. ScHUL'rz,.a citizen of the United States, residing at New York, in the county and State of'New York, have invented new and useful Improvements in Process of Collecting and Utilizing Oarbonic-Acid Gas from Acidulous Springs, of which the following is a specification.

This invention consists in a new and im-;

proved process of obtaining large quantities of carbonic-acid gas from acidulous mineral springs, which can be made use of for impregnating the waters of such springs when hottled with any desirable excess of that gas, or:

for any other technical operation in which carbonic acid can be used.

The process is based upon the varying affin temperatures, While its affinity for cold wa-' ter is so strong that many cold springs contain considerably over one volume of carbonicacid gas in solution near their surface, it gets rapidly less and is evolved fromthe water as its temperature rises, hot water not being able to retain any considerable amount of carbonicacid gas in solution. 4 r

In order to apply the above principle, a'sufficient proportion of the water flowing or obtained from any acidulous spring is conveyed in some suitable manner into a closed generating-vessel of sufficient size, which has a watersealed overflow-pipe, and on the top another pipe, through which the carbonic-acid gas can be conveyed to any desirable point. The acidulous water, on its passage through the generating-vessel, is heated by means of a'steamcoil orin any suitablemanner, when thecarbonic acid dissolved in the water will be rapidly expelled from it and collect over its surface, whence it can be conveyed through the gasescape pipe into a gas-holder and stored for further use, or directly to machines which are used for the impregnation of water with any desirable excess of such gas,.making such water highly effervescent and of improved taste and value.

It is most advantageous that the cold water should enter the generating-vessel near the bottom- The temperature to which the water should be heated is optional, and depends upon the supply and the strength of the natural water.

The principal portion of the gas will be excated by a milky appearance of the water as it flows from the overflow-pipe of the generatingvessel. Natural mineral waters containing only one volume of carbonic-acid gas in solution can thus be easily bottled with a large excess of gas obtained from the spring, and made highly effervescent by using the carbonicacid gas thus obtained from two or three parts of the yield of the spring and impregnating therewith one part of the natural water. The quantity and proportion of the natural water needed for the supply of gas will of course diminish as the same may be richer in carbonic acid. The gas thus obtained will be in all respects the same as the gas which remains absorbed by the natural water, and will be superior to the natural gases which are exhaled-7 5 from springs, and which often have a dilferent composition, being mixed with other gases,

- especially with nitrogen and carbureted hydrogen.

If the preservation of the original proportion of solid mineral substances in a natural water be not desirable, a steam-coil can be inserted directly into the spring some little distance below the surface of the water, and the gas thereby evolved can be collected in a gasholder, which is sealed by the water of the spring. In this case that portion of the yield of the spring required for bottling would have to be conveyed into an open cooling-tank, in which objectionable ingredients would precipi- 9o tate and thus be removed from the water. The subsequent impregnation of the water with an excess of carbonic-acid gas is the same in either case.

Heretofore it has been proposed to collect 5 the'waste gas escaping from a mineral spring by collecting the same in areservoir arranged overthe spring; butsuchisnotbroadly claimed by me.

The apparatus which may be used in carry- 10o ing out my invention is illustrated in the accompanying drawings, in which- Figure 1 represents a section of the generator in which the water from an acidulous spring is heated. Fig. 2 is a section of an acidulous well with a heating-coil and a vessel for collecting the carbonic-acid gas.

In Fig. 1, the letter A designates the genersiting-vessel, which is provided with a supplypipe, 0;, and an overflow-pipe, I), provided with it water-seal, e, to prevent the escape of gas. Near the bottom of said vessel is the heatingcoil d, and from the top of the vessel extends the gasescnpe pipe 0. As the water from on acidnlons spring is caused to 110w slowly through the vessel A it becomes heated by the coil (1, and the gas which is driven out of the water by the heat passes 011' through the pipe 6 into a gas-holder or directly to the impregimtin z; apparatus.

When the water is to be heated directly in the well, as stated in the foregoing description,

placed the inverted vessel 1), which is provided with a gas-escape pipe, E. When the water is heated the gas contained therein is driven out and the largest portion thereof collects in the vessel E, whence it is conducted to the impregnating apparatus.

What 1 claim as new, and desire to secure by Letters Patent, is

l. The within-described process of obteinin g carbonic-acid gas from neidulous mineral springs by expelling from such water the curhonie-acid gas by the notion of heat and collooting such gas in a suitable gasholder, substantially as and for the purpose set forth.

2. The within-described method of impregnating mineral waters with carbonic-acid gas, which consists in first driving out the said gas from the water either in the spring or already collected therefrom by the action of heat applied to such water, and then forcing the gas so collected into a quantity of water taken direetlyi'roin the same source in testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
